SPECIFICATION forming part of Letters Patent No. 618,172,A dated January24, 1899.

Application filed February 7, 1898. Serial No. 669,446. (No model.)

To all whom, t ntoty concern:

Be it known that I, BYRON B. GoLDsMrrH, a citizen of the United States,and a resident of New York, in the State of New York, have inventedcertain new and useful Improvements in Magazine Lead-Pencils, of whichthe following is a specification.

This invention has reference to improvements in magazine lead-pencils ofthat class in which a number of marking-points are stored within themagazine and suitable mechanism is provided for projecting themarking-points one by one into position for use, while at the same timeworn or broken points are ejected from the pencil. Magazine-pencils ofthis class as heretofore made were more or less complicated instructure, due, among other things, in some cases, to the presence ofsprings, which were deemed necessary in order to make the operation ofthe pencil automatic to a certain extent.

The present invention avoids the use of springs to assist in theoperation of the pencil, and l am thereby enabled to simplify thestructure and operation of multipoint magazine lead-pencils to a markeddegree.

The improved 'pencil consists, essentially, of two parts-namely,amagazine with springjaws at the front capable of being clamped tightlyupon a point that has been projected into position for use and a mantleupon and movable along the magazine and carrying an ejector normallyentering the magazine, but capable of being withdrawn therefrom.

The construction and operation of the improved pencil will be understoodfrom the following detail description, taken in connection with theaccompanying drawings, in which#- Figure lis an elevation of one formof'pencil. Fig. 2 is a longitudinal section of the same. Fig. 3 is asimilar view, but partly broken away,showin g the position of the partsduring a different period of operation than that shown in Fig. 2. Fig. 4is an elevation of the front portion of the magazine. Fig. 5 is anelevation of the ejector attachment of the mantle. Fig. 6 is anelevation of a modiiied form of the pencil, and Fig. 7 is a longitudinalsection of the form of pencil shown in Fig. 6.

Referring to the drawings, there is shown a magazine-tube l of such sizeas to freely receive a series of sharpened marking-points 2, preferablyof conical shape. The forward end of the magazine-tube is slottedlongitudinally, as shown at 3, to form two springjaws 4 4. These jawsare in the shape of two cone frusta 4 1l", joined at the bases, atl

which point they are of greater diameter than the main body of themagazine-tube. The jaws are normally slightly open and are soproportioned that the front conical portion 4 conforms in shape to amarking-pointand permits the latter to project a little more than halfits length, and when these jaws are closed in the manner to be presentlyexplained they grasp the butt-end of the marking-point with firmpressure.

Surrounding the magazine there is a mantle so much shorter than themagazine that the latter can easily be grasped in the fingers of onehand, while the other hand is used to manipulate the mantle in a mannerto be described farther on. The mantle is composed of a tube 5 ofsuitable length, but considerably shorter than the magazine-tube, andanother still shorter tube 6, inserted into the front end of the tube 5.

The tube 6 has its front end spun over the front edge of the tube 5 andmay be held in place within the tube 5 by solder or simply by friction.A spring-linger 7 is formed integral with the tube G and projects beyondthe front edge of the same and also extends back a short distance intothe body of the tube, as shown in Fig. 5,while the outer tube 5 has anarrow longitudinal slot 8, here shown as opening through the front edgeof the tube. This slot or recess allows the iinger to move slightlyoutwardly through the mantle for a purpose that will presently appear.

The mantle is so constructed and is so mounted upon the magazine as tobe capable of being moved longitudinally thereon fora limited distance.This movement of the mantle upon the magazine is for the purpose ofmoving the spring-linger 7 into and out of the magazine through a slot 9therein and also for the purpose of closing the spring-jaws 4 to clamp amarking-point between them. The slot 9 is simply a widened or enlargedportion of one of the slots 3, separating the jaws 4, and extends fromthe main body of IOO the magazine-tube into the rear conical portion 4"of the jaws. The finger 7 is curved inwardly, so as to normally extendthrough the slot 9 into the magazine-tube. Vhen the mantle is movedtoward the forward position, the front edge of the slot 9 engages thetop of the curved portion of the finger, causingV it to bend inwardlyuntil it ultimately engages the opposite side of the jaws. When themantle is moved rearwardly, the rear edge of the slot 9 engages theunder sideof the nger, lifting it suliciently to clear the interior ofthe magazine, the slot 8 of the tube 5 permitting this outward movementof the finger. When the mantle is moved forward the front endthereof,made rounded and rigid by the bead formed by spinning the end ofthe tube 6 over the front end of the tube 5, rides along the conical oroutwardly-inclined portion 4" of the jaws and forces the lattertogether, the internal diameter of the mantle being for this purposemade sufliciently less than the normal external diameter of the largestportion of the jaws.

The rear end of the mantle slides upon and is supported by a sleeve 10,fast on the exterior of the rear portion of the magazine-tube and ofsuch length as to be engaged by the rear end of the tube 6 when themantle is moved rearwardly a distance sufficient to draw the spring-nger7 out of the interior of the magazine. This sleeve therefore acts as astop limiting the rearward movement of the mantle.

The rear end of the sleeve 10 is screwthreaded to receive ascrew-threaded cap 11, serving as a closure for the rear end of themagazine. On removing this cap the magazine maybe filled withmarkingpoints,which are inserted with the sharpened end foremost. If nowthe mantle is drawn back until the spring-finger is out of the magazineand the pencil is held with the jaws downward, the points will falluntil the forward point has lodged in the jaws,with about half of itslength protruding therethrough, and will be gently held in this positionby the jaws. On inverting the pencil the other points will fall backtoward the rear end of the magazine. Vhile the pencil is held in thisinverted position the mantle is pushed forward, causing the finger 7 toenter the magazine through the slot 9 until it ultimately comes incontact with the butt-end of the point lodged in the jaws. The front endof the mantle at the same time rides along the inclined or conicalportion 4" of the jaws and forces the latter together until they havefirmly clamped the marking-point in the writing position.

When the pencil is in use, the projected marking-point cannot be forcedinto the magazine by the pressure of the act of writing, this beingprevented by the linger 7 ou the mantle, the finger 7 acting as a stop,and the tendency of the mantle to slide forward on the jaws closes themstill tighter on the proj ected marking-point, while the spring-finger,

moving with the mantle,forces the point more rmly between the jaws.

When the projected marking-point has become worn orbroken and it isldesired toproject a new point into position for use, the mantle ispulled backward until the finger 7 is withdrawn from the magazine. Thepencil is now so placed that the marking-points will fall by gravityuntil the second point is in contact with the first or projected point.The mantle is now moved forward, and the finger 7, entering themagazine, comes in contact with the butt-end of the second point beforethe front end of the mantle has reached the conical section 4'. of thejaws. A continued forward movement of the mantle causes the second pointto force the rst point through and out of the front end of the jaws, thelatter being elastic enough for this purpose, and the second point isultimately by the same forward movement of the mantle projected throughthe jaws and the latter clamped upon it in the manner heretoforedescribed. The finger 7 in this case acts as an ejector.

W'hen all the points have been used, a new supply may be inserted in themagazine after the screw-cap 11 has been removed.

It will be seen from the foregoing description of the operation of thispencil that every new marking-point after having been brought betweenthe clamping jaws is positively clamped between the same and issimultaneously therewith pushed home with increasing force and that theact of Writing tends to still more firmly push the point between thejaws and at the same time force the latter more rmly together.Aloosening of the markingpoint during or by the act of writin g isthereby positively prevented. It will also be seen that thespring-iinger 7 has the double function of a stop for preventingrearward movement of a projected marking-point when the pencil is in useand an ejector for expelling worn or broken points from the pencil.

The modified form of pencil shown in Figs. 6 and 7 is in operation andgeneral construction the same as that already described. The outer tube5 of the mantle is replaced by a sleeve 5 of cork or other similarmaterial, forming a pleasant surface to grasp in the fingers. Thescrew-cap 11 is replaced by a cap 11 of wood or other suitable material,shaped like the rear end of a penholder. This cap l1' has its front endbored out longitudinally, and a threaded sleeve 12 is inserted in thebore to engage the threaded end of the sleeve 10, fast on the magazine.There is a sleeve 13 fast on the rear end of the cork sleeve 5' andconstituting a continuation of the mantle. This sleeve 13 is of suchdiameter and length as to receive the front end of the cap 11 and hidethe same from view, thus giving the pencil a finished appearance.

In the form of magazine-pencil shown in Figs. 6 and 7 it is notnecessary to provide the sleeve 5 with a slot corresponding to the IOOIIO

slot 8 in the tube 5 of the form shown in Fig. l, since the elasticityof the cork sleeve 5 permits the finger 7 to move outwardly on beingwithdrawn from the magazine.
